Mechanical pump leak

[Chuko]

I’m currently having an issue with my mechanical fuel pump. Well there’s seems to be a little hole on the bottom side of the pump is that supposed to be like that open like that fuel drips out of it when I have the truck running somebody tell me why

The diaphragm inside is split. You need a new pump. Its not fixable. The hole is a vent and is supposed to be there.

Its probably associated with the fact that you're dumping about 4x the
normal amount of fuel into the engine.

Check your spark plugs. Probably sooty black. If so, too much carb/fuel

Is this the same truck you say "Runs Great" in a For Sale ad?
